Dynamic caching system

ABSTRACT

A computer implemented system and method for implementing a dynamically correcting cache is disclosed. The dynamically correcting cache is capable of correcting itself by dynamically reflecting any modifications inflicted upon the data/information to be stored in the cache memory. Further, the cache memory is refreshed at predetermined time intervals and also based on predetermined criteria, thereby ensuring a high cache hit rate. The dynamically correcting cache memory is bypassed for certain user queries prioritized based on a predetermined criteria. The dynamically correcting cache manages an inventory shared between multiple non-cooperative web-based, computer-implemented platforms. The dynamically correcting cache is directed to reducing caching errors in web based computer implemented platforms. The dynamically correcting cache responds to rapid changes associated with (online) behavior of users accessing web based computer implemented platforms by dynamically configuring TTL (Time-To-Live) values, in order to ensure that the data/information stored in cache memory remains accurate.

BACKGROUND

Technical Field

The present disclosure relates to caching systems implemented in web based computer systems. Particularly, the present disclosure relates to caching systems operable in a networked environment incorporating non-cooperating computer systems.

Description of Related An

Web based travel platforms and web based commerce platforms are typical examples of non-cooperating systems implemented in a networked computing environment Aforementioned Platforms link suppliers to customers via dedicated programmed interfaces and enable customers to inter-alia query for, search, review, and select the products/services on offer, in addition to enabling suppliers to offer products/services for sale.

In a typical networked computing environment, either a ‘push model’ or a ‘pull model’ is utilized to provide to customers the data and information corresponding to the products/services on offer, In case of a push model, suppliers publish the information corresponding to the products/services on offer, on various programmable interfaces. Push model is effective in scenarios where there are a limited number of suppliers offering products/services to customers, and also in scenarios where the products/services on offer are not. known to be seasonal and fast moving.

In case of a pull model, a centralized data repository stores the data and information corresponding to the products/services offered (by respective suppliers) via various programmed interfaces, to customers. Subsequently, programmed interfaces access the centralized database via dedicated APIs (Application Program Interface), to receive and display (to the customers) the products/services on offer, preferably along with relevant information such as availability, price, and the like.

For example, a web based programmed interface (portal) offering hotel accommodation to customers typically employs the ‘push model’, wherein all the data and information corresponding to available hotel accommodations is uploaded on to a centralized repository. Subsequently, various programmed interfaces access the centralized repository via dedicated APIs, preferably in order to respond to a query pertaining to hotel accommodations. Typically, a query pertaining to hotel accommodations comprises information corresponding to check-in date, check-out date, preferred destination, preferred class of service, and level of occupancy. A typical answer to such a query would include information corresponding to the pricing and availability of relevant hotel accommodation.

Typically, hotel accommodations prices are decided by suppliers based on the class of service preferred by customers, dates preferred by customers and the corresponding occupancy rates inter-alia. Further, pricing of hotel accommodations is also impacted by the time period during which the hotel accommodation is requested and also based on the duration of time for which accommodation is requested. Hotel accommodations are priced dynamically based on a plurality of factors including check-in date, check-out date, preferred destination, preferred class of service, and level of occupancy. And further, it is common that the pricing strategy followed by suppliers changes with a change in any of the aforementioned factors.

Therefore, in order to accommodate dynamicity in the pricing strategy and to accommodate any rapid modifications in pricing strategy, and also to enhance user experience. any programmed interface catering, to the demands for fast moving services is compelled to maintain a caching platform for storing information that is frequently accessed/queried for by customers. In a typical networking environment, individual cache memory modules are maintained every programmed interface offering products/services for sale. Each of the said cache memory modules derive data and information from a centralized repository which incorporates the information typically provided by the suppliers of products/services, and required to be displayed on the programmed interfaces.

Cache memory nodules dedicated to individual programmed interfaces are a necessity given the need for frequently accessed/frequently queried information to be provided to users (of programmed interfaces) within a shortest possible response time. In order to achieve shortest possible response time, and thereby enhance the user experience, programmed interfaces store the frequently accessed information in dedicated cache memory modules. Typically, any frequently accessed/frequently queried information is retrieved from corresponding cache memory module for display by programmed interfaces. Individual cache memory modules communicate with the centralized repository, typically after elapse of a predetermined time interval, to ensure that the information stored therein accurately corresponds to the information (originally provided by suppliers) stored in the centralized repository. In the event that the information stored in the centralized repository is modified, the individual cache memory modules are updated about the modifications (to the information stored in the centralized repository) at pre-determined time intervals by dedicated APIs which are used by programmed interfaces to access the centralized repository.

Typically, in the event that the information provided by the supplier is to be modified, for example, an increase/decrease in prices of hotel accommodation during a festive season, or changes in availability levels of hotel accommodations corresponding to a particular class of service, the supplier reflects the modifications on the information stored in the centralized repository. The modifications reflected on the information stored in the centralized repository are subsequently reflected upon corresponding frequently accessed/queried information stored in individual cache memory modules. The information stored in individual cache memory modules is typically associated with a pre-calculated TTL (Time-To-Live) period. After the expiry of the TTL period, the cache memory modules access the centralized repository to check for and selectively incorporate any updates/modifications inflicted on the information originally stored in the centralized repository.

However, the complexity associated with calculating an ideal TTL increases with an increase in the rate at which the information (provided by the supplier) stared in the centralized repository is modified. With the information stored in the centralized repository being modified repeatedly (either by suppliers, or due to changes in inventory levels, or due to a surge/decrease cache memory modules with modified information, if it is determined that the updates reflected on the centralized repository are found to have implications on the frequently accessed/queried information stored in individual cache memory modules. However, pre-calculating a TTL value by forecasting the rate at which the centralized repository might be updated is a challenging task yet to be efficiently addressed.

Further, caching system already known in the art typically implement a TTL (Time-To-Live) period based scheme which includes defining a TTL for every data item (dab point) stored in a repository. Subsequent to a query being raised for retrieving certain data items from the repository, the data items retrieved (from the repository) as a response to the query are assigned a TTL period and stored in a cache memory module. The TTL period is typically decided on an ad-hoc basis and ranges between 2 hours to 24 hours. However, the TTL period based scheme envisaged by prior art caching system does not take into account the volatility associated with querying for data items. For example, the number of queries corresponding to a small yet popular hotel could exceed the number of queries corresponding to a large hotel. Further, queries directed to air travel scheduled a week ahead would obviously exceed the number of queries directed to air travel scheduled a fortnight ahead.

In view of the foregoing there is felt a need for a system that calculates and implements TTL values in such a way that the volatilities associated with the information stored in caching memory modules are efficiently addressed, without having a hearing upon usability of programmed interfaces.

SUMMARY

The present disclosure envisages a dynamic caching system. The dynamic caching system is communicably coupled to a master database which stores repetitively accessed data points. The master database is simultaneously accessible to a plurality of computer implemented platforms, preferably non-cooperative computer platforms. The master database transmits the frequently accessed data points to the caching system. The caching system subsequently receives the frequently accessed data points. The caching system includes a user engine configured to receive a query from a user of computer implemented platform. The received query is subsequently processed by an orchestrator. The orchestrator selectively searches the caching system for (stored) data points relevant to the query. Subsequently, the orchestrator retrieves data points deemed relevant to the query.

The data points retrieved by the orchestrator are subsequently processed by a decision engine. Subsequent to processing retrieved data points, the decision engine determines the cache age corresponding to each of the retrieved data points. The cache age (of data points) is a difference between the time when the relevant data points were received into the caching system from the master database and the time when the relevant data points were retrieved from the caching system by the orchestrator. The decision engine dynamically sets determined cache age as a Time to Live (TTL) period for the query corresponding to the relevant data points, such that every query directed to said relevant data points within said cache age incorporates an accuracy measurement equivalent to a predetermined value.

DETAILED DESCRIPTION

To obviate the disadvantages and drawbacks discussed in the ‘background’ section, the present disclosure envisages a dynamic caching system. The dynamic caching system envisaged by the present disclosure provides a dynamic TTL based scheme involving defining a (data) accuracy target for each response linked to a data query, and setting a separate TTL period for data points incorporated in the said response.

Referring to FIG. 1, there is shown a dynamic caching system 100. The caching system 100, in accordance with the present disclosure includes a master database denoted by reference numeral 10. The master database 10 is preferably accessed by a plurality of computer implemented platforms, preferably non cooperative computer implemented platforms which are oblivious to the functioning of other similar computer implemented platforms. The computer implemented platform can be one of an online travel portal or an online marketplace or an online travel aggregator or an online provider of bus/rail/air tickets. For the sake of brevity, FIG. 1 illustrates only one non-cooperative computer implemented platform 16, which cooperates with the master database 10 to receive data and information necessary for its implementation and functioning. The data items relevant to the functioning of the computer implemented platform 16 include but are not restricted to information corresponding to availability of commodities for purchase and the corresponding price, information corresponding to availability of air/rail/bus tickets and corresponding prices, information corresponding to availability of hotel accommodation and corresponding prices.

The caching system 100, in accordance with the present disclosure further includes a cache memory module denoted by reference numeral 12. Preferably, every computer implemented platform manages a dedicated cache memory module. However for ease of explanation, only one cache memory module 12 and only one computer implemented platform 16 has been illustrated in FIG. 1, and the corresponding description. The cache memory module 12 creates and manages a replica/copy of the information which is stored in the master database 10 and frequently queried/accessed by the computer implemented platform 16. The frequently queried/accessed information is stored as data points, in the cache memory module 12. Typically, whenever a query from a computer implemented platform 16 is directed to any of the frequently accessed data points, the said frequently accessed data points are retrieved directly from the cache memory module 12 instead of querying the master database 10.

In accordance with the present disclosure, the computer implemented platform 16 (referred to as ‘platform’ hereafter) is accessible to a user 14. In an exemplified scenario, the user 14 launches a query for a product/service being sold/made available on the computer implemented platform 16. The query generated by the user 14, for example, may be directed towards booking a hotel accommodation in a metro city for three people. The said query form the user 14, is transmitted to the platform 16 via a user interface (not shown in figures). Subsequently, the user engine 18 processes the query generated by the user 14, and transmits the query to an orchestrator 20 for further processing.

The orchestrator 20 subsequently processes the query and determines whether the data points relevant to the said query are to be fetched from the cache memory module 12 or whether the data points relevant to the said query are to be fetched from the master database 10. The orchestrator 20 cooperates with an accuracy engine 22 to determine whether to bypass the cache memory module 12 and retrieve the data points from the master database 12, or otherwise. The accuracy engine 22 determines, preferably dynamically, an accuracy value for every query directed to the master database 10 as well as the cache memory module 12. For example, any query deemed to materialize into a sale would be allocated an accuracy value of 97%, and any query that is deemed to correspond to only online browsing would be allocated an accuracy value of 80%. The queries that are deemed to materialize into sales are assigned a higher accuracy value, by the accuracy engine 22.

Typically, queries that correspond to on-line purchasing (queries that are deemed to materialize into a product/service sale) are accorded a higher accuracy value and directed to the master database 10 which always maintains updated data necessitated by the platform 14, while bypassing the cache memory module 12. Further, queries that do not materialize into a sale and correspond to only online browsing are accorded a lower accuracy value and directed to the cache memory module 12. Before deciding to bypass the cache memory module 12 in case of queries corresponding to online purchasing, the accuracy engine 22 takes into consideration the purported penalties to be incurred (financial or otherwise) in case of retrieving inaccurate data points in respect of the query, and the data coverage provided by each of the data points considered pertinent to the query.

Subsequently, if it is decided (by the accuracy engine 22) that the data points relevant to the query are to be fetched from the master database 10, then the orchestrator 20 generates a ‘cache miss’ signal and transmits the ‘cache miss’ signal to the cache memory module 12 thereby a cache memory bypass. Subsequently, the orchestrator 20 fetches the data points (deemed pertinent to the query) from the master database 10, and renders it to the user 14 via the user engine 18. The orchestrator selectively updates the cache memory module 12 with the data points (deemed pertinent to the query) retrieved from the master database 10. Further, if the orchestrator 20 determines that the data points relevant to the query are to be procured from the cache memory module 12, then the orchestrator 20 accesses the cache memory module 12 through a data engine (not shown in figures) and retrieves via the data engine the said relevant data points from the cache memory module 12.

The caching system 100 in accordance with the present disclosure further includes a deduplication engine 24. The deduplication engine 24 cooperates with the orchestrator 20 to receive the relevant data points. The data points typically include static data as well as dynamic data. The deduplication engine 24 processes the relevant data points retrieved by the orchestrator 20, and identifies static data and dynamic data from the relevant data points. Static data includes data that does not change based on the nature of a query. An example of static data in the context of hotel accommodations would be the data corresponding to ‘description of the hotel’ and the ‘address of the hotel’. Further, dynamic data includes data that does change depending upon the nature of the query. An example of dynamic data in the context of hotel accommodations would be the data corresponding to ‘pricing of hotel accommodations’, and ‘availability of hotel accommodations’. Further, the deduplication engine 24 preferably interlinks at least the dynamic data embedded in the relevant data points, with the corresponding query. Further, the dynamic data embedded in the relevant data points, and the query linked thereto are stored in a log engine 26.

In accordance with the present disclosure, in the event that the orchestrator 20 determines the data points stored in the cache memory module to be irrelevant/inaccurate with reference to the query, the orchestrator 20 triggers a similarity engine 28, and instructs the similarity engine 28 to search for data points pertinent to the query specified by the user 14. The similarity engine 28, in accordance with the present disclosure cooperates with the master database 10 and identifies, from the master database 10, the data points that can be enlisted as an accurate/relevant response to the query provided by the user 14. Additionally, the similarity engine 28 also identifies data points neighboring the data points deemed relevant to the query of the user, as being relevant. The similarity engine 28 identities any pair of data points as similar if both the data points are accessed within a same predetermined time frame, or if the values of both the data points change with a same predetermined time frame. Subsequently, the data points enlisted by the similarity engine 26 as being relevant to the query are stored in the log engine 24 along with the relevant data points retrieved by the orchestrator 20 from the cache memory module 12.

In accordance with the present disclosure, a feedback engine denoted by reference numeral 30 cooperates with the log engine 24 and continuously analyzes the queries and the data points stored in the log engine 24. The feedback engine 30 compares the data points retrieved from the cache memory module 12 in response to a query provided by the user 14, with similar data points stored in the master database 10, and determines whether the data points stored in the master database system 10 are as accurate as the data points retrieved from the cache memory module 12, with reference to the query. Subsequently, the feedback engine 30 combines the data points retrieved from the master database 10 with the data points stored in the cache memory module 12, only in the event that the data points retrieved from the cache memory module 12 are determined to be inaccurate in view of the query. Further, the feedback engine 30 selectively deletes the data points (stored in the cache memory module 12), whose age has exceeded a predetermined threshold value.

In accordance with the present disclosure, the feedback engine 30 compares the data points (stored in the master database 10) identified by the similarity engine 26 as relevant to the query provided by the user 14, with the data points stored in the cache memory module 12 and deemed relevant to said query. The feedback engine 30 determines whether the data points stored in the cache memory module 12 are as accurate as the data points identified by the similarity engine 26. The feedback engine 30 combines the data points retrieved from the cache memory module 12 with the data points identified by the similarity engine 28, only in the event that the data points retrieved from the cache memory module 12 are determined to be inaccurate, with reference to the query provided by the user 14.

In accordance with the present disclosure, the caching system 100 further includes a pre-fetch engine 32. The pre-fetch engine 32 cooperates with the similarity engine 28 and cache memory module 12. The pre-fetch engine 32 loads the data points identified by the similarity engine 28, onto the cache memory module 12. Further, the pre-fetch engine 32 selectively implements a data refresh function for the data points stored in the cache memory module 12, based on at least one of frequency of access/querying of data points, utility of each of the data points in terms of answering a query generated by the user 14, and relevance of each of the data points to the query generated by the user.

Subsequently, the query provided by the user 14, and the data points identified by the similarity engine 28 and the orchestrator 20 are stored in the log engine 24. The orchestrator 20 subsequently retrieves from the log engine 24 the data points relevant to the query provided by the user 14, and subsequently renders the retrieved data points to the user 14 via the user engine 18 communicably coupled to the platform 14.

The caching system 100, in accordance with the present disclosure further includes a decision engine 34. The decision engine 34 cooperates with the orchestrator and identifies the data points deemed as relevant, by the orchestrator 20, to the query provided by the user 14. The decision engine 34 subsequently determines a cache age corresponding to the data items deemed as relevant by the orchestrator 20. The cache age is a difference between the time when the relevant data points were received into the cache memory module 12 from the master database 10 and the time when the relevant data points were retrieved from the cache memory module 12 by the orchestrator 20. The decision engine 34 further sets the cache age as a Time to Live (TTL) period for the query corresponding to the relevant data points (identified by the orchestrator), such that every query directed to said relevant data points within said cache age satisfies an accuracy value predetermined by the accuracy engine 24.

Referring to FIG. 2, there is shown a flow chart illustrating the steps involved in the method for implementing a dynamic caching system. The method, in accordance with the present disclosure comprises the followings steps:

-   -   receiving a query from a user of a computer implemented         platform, via a user engine (200);     -   processing the query using an orchestrator (202);     -   selectively searching the cache memory module, using the         orchestrator, for data points relevant to the query and         retrieving, relevant data points therefrom (204);     -   processing the relevant data points using a decision engine, and         determining cache age based on the relevant data points, the         cache age being a difference between the time when the relevant         data points were received into the caching system from the data         inventory and the time when the relevant data points were         retrieved from the cache memory module (206); and     -   dynamically assigning the cache age as a Time to Live (TTL)         period for the query corresponding to the relevant data points,         such that every query directed to the relevant data points         within the cache age satisfies a predetermined accuracy value         (208).

In accordance with the present disclosure, the method further includes the following steps:

-   -   selectively loading the data points stored in the master         database and identified as similar to the data points retrieved         from the cache memory module, onto the cache memory module,         using a pre-fetch engine;     -   loading onto the cache memory module via the pre-fetch engine,         the data points bound to expire after elapse of a predetermined         time interval but deemed relevant to the query; and     -   selectively implementing a data refresh function for the data         points stored in the cache memory module, using the pre-fetch         engine.
